A number labeled stage describes water level relative to a reference. A number labeled flow describes volume passing a point over time. Neither number counts damaged properties. This guide uses the Neuse River at Smithfield, North Carolina, to show how to read those quantities. The gauge identity and thresholds come from NOAA records checked on October 28, 2026. The worked readings are fictional training examples. They are not a current weather briefing. Use the [restoration company overview](/for/restoration-and-water-fire-damage) for the separate office work that follows a reported loss. Here, the task is narrower: prepare a source-grounded explanation of a river hydrograph before a manager discusses readiness. ## Identify the gauge before reading the curve A hydrograph describes conditions at a particular location over time. The [NWPS hydrograph guide](https://water.noaa.gov/about/hydrograph) distinguishes the observed record from forecast information. Read the location and legend before comparing heights or colors. The [Smithfield gauge metadata](https://api.water.noaa.gov/nwps/v1/gauges/SMFN7) identifies the location as Neuse River at Smithfield. Its NWPS identifier is `SMFN7`; its USGS identifier is `02087570`. Preserve both identifiers when someone also uses a USGS page. A place name alone is a weaker way to confirm that two colleagues are discussing the same gauge. Begin a meeting note with the gauge name, identifier, source link, and reading time. Add the quantity and unit beside each value. Keep the forecast separate from the observations, even when both appear on one chart. Do not substitute a different gauge because its town name seems familiar. If a colleague presents another location, pause the comparison until the location is resolved. The same river name does not make two gauge references interchangeable. For this reading exercise, Smithfield is an identified example, not a recommendation for every restoration company's territory. Your responsible local reviewer must decide whether a gauge belongs in your preparation discussion. The chart does not establish that business relationship for you. ## Stage measures height relative to a reference NOAA defines stage as water-surface level measured relative to a datum. At Smithfield, the retrieved stageflow response labels the primary quantity `Stage` and its unit `ft`. Read a stage value as feet relative to the gauge reference, not feet above a customer's floor. See the [hydrograph definitions](https://water.noaa.gov/about/hydrograph) and [Smithfield series](https://api.water.noaa.gov/nwps/v1/gauges/SMFN7/stageflow). The distinction is practical. A stage of 14.5 feet is a gauge reading. It is not a statement that water is 14.5 feet deep throughout Smithfield. It also does not establish the depth of water inside any building. The [gauge metadata](https://api.water.noaa.gov/nwps/v1/gauges/SMFN7) includes vertical-datum information labeled NAVD88. Preserve the published reference when quoting elevation information. Do not relabel a stage value as an elevation above sea level or combine it with an unrelated building elevation. In a readiness meeting, you normally need the stage and its matching local threshold. You do not need an improvised conversion to building conditions. Leave elevation reconciliation and site interpretation with qualified people using the appropriate records. Ask the presenter to finish this sentence: “This value measures water level at this gauge, relative to this reference.” If the reference is missing, retain that gap. A polished chart cannot supply the omitted meaning. ## Flow measures volume per unit of time Flow answers a different question: how much water passes a point during a period. NOAA defines `kcfs` as thousands of cubic feet per second. The prefix changes the scale, not the type of quantity. [NWPS definitions](https://water.noaa.gov/about/hydrograph) describe both flow and kcfs. In a synthetic conversion exercise, 4.2 kcfs equals 4,200 cubic feet per second, or cfs. That is unit arithmetic only. It is not an observed Smithfield reading or a proposed flow corresponding to the stage example below. Keep that separation because stage and flow are not interchangeable numbers. NOAA explains that river forecasts use a relationship between stage and flow at each specific gauge. A manager should not infer that relationship from a pair of labels or apply one location's relationship elsewhere. See NOAA's [river forecasting explanation](https://www.noaa.gov/jetstream/rfcs). Smithfield illustrates a useful reading trap. The retrieved series labels flow in `kcfs`, while the gauge record's flood metadata labels its flow units `cfs`. These are different response sections. Inspect the unit attached to the particular field you are using. The [metadata](https://api.water.noaa.gov/nwps/v1/gauges/SMFN7) and [series](https://api.water.noaa.gov/nwps/v1/gauges/SMFN7/stageflow) must be read together. The flood-category flow fields in that metadata contained `-9999` when checked. This guide does not treat those values as usable flow thresholds. The worked example uses the explicitly supplied stage thresholds instead. Preserve the missing interpretation rather than inventing a flow equivalent. ## Read action stage separately from flood categories Action stage is a preparation reference. NOAA describes it as a level on a rising water body where the NWS or a partner needs a mitigation action. It is distinct from the minor, moderate, and major flooding categories. The applicable local action is not supplied by the number alone. See the [official terminology](https://water.noaa.gov/about/hydrograph). In NOAA's general descriptions, minor flooding can involve little property damage while still posing a public threat. Moderate flooding includes inundation of some structures or roads. Major flooding describes extensive inundation and larger evacuation or property-transfer consequences. Those category descriptions are broad. They do not certify the status of any customer location. For Smithfield, the gauge metadata supplied the following stage thresholds on the source-access date. Table: Smithfield stage thresholds checked on October 28, 2026 | Published reference | Stage in feet | How to label it in the meeting | | --- | --- | --- | | Action | 14 | Action-stage threshold at SMFN7 | | Minor | 15 | Minor-flood-stage threshold at SMFN7 | | Moderate | 18 | Moderate-flood-stage threshold at SMFN7 | | Major | 20 | Major-flood-stage threshold at SMFN7 | Source: [SMFN7 flood categories](https://api.water.noaa.gov/nwps/v1/gauges/SMFN7), `flood.stageUnits` and `flood.categories`. Reopen the metadata before an operational briefing; this table is a dated reading example. Keep the threshold labels intact. Replacing “below minor flood stage” with “safe” changes the claim. Replacing “action stage” with “confirmed property damage” also changes it. Neither substitution follows from the published thresholds. ## Work through one fictional Smithfield reading Assume a training sheet contains an observed stage of 14.5 feet at SMFN7 at a clearly labeled practice time. It also contains an earlier fictional observation of 13.8 feet. The two observations use the same gauge and stage reference. The later stage is 0.5 feet above the checked action threshold and 0.5 feet below the minor threshold. It is 0.7 feet higher than the earlier training observation. Those differences are arithmetic applied to invented readings and the dated official thresholds. A useful meeting statement would be: “In this exercise, Smithfield stage increased between the two observations and is above action stage, below minor flood stage.” That statement preserves the location, comparison, and category boundary. Now add a fictional forecast point of 15.6 feet for a later valid time. That point lies above the checked minor threshold and below the moderate threshold. Label it forecast throughout the discussion. Do not change the observed stage to 15.6 feet because that is the largest visible value. The two pieces of evidence support two separate sentences. The observations describe the exercise's measured sequence. The forecast describes a predicted value for its own valid time. The [forecast timestamp guide](/articles/river-forecast-issuance-valid-time-shift-handoff) explains how to preserve that distinction across shifts. Do not call the 15.6-foot point the forecast crest unless the source identifies it appropriately or you have checked the complete relevant curve. One selected point cannot establish what happens before or after it. If your handout shows only one point, say so. ## Read the curve's shape without inventing a timetable Ask whether you are looking at a rising observed sequence, a falling sequence, or only one isolated reading. Then identify where observations stop and forecasts begin. A line drawn through points does not erase that boundary. NOAA's [forecasting explanation](https://www.noaa.gov/jetstream/rfcs) describes runoff, upstream contributions, and the time water takes to move through a basin. Rain ending locally does not, by itself, establish that a downstream river has finished rising. That is why the meeting should refer to the published forecast rather than a personal estimate from recent weather. Avoid extrapolating the fictional 0.7-foot increase into a fixed hourly rise. Two selected points are not a reviewed forecast model. Keep the observed interval visible, and use official forecast information for the forecast portion of the discussion. If a forecast is missing, record that condition explicitly. NWPS explains that forecast availability varies by location and circumstances. An absent curve cannot establish low risk. The [hydrograph guide](https://water.noaa.gov/about/hydrograph) describes that availability distinction. ## Translate the reading into questions for responsible people A readiness meeting can ask whether the company's availability records need review. It can ask which manager will check current official information before the next shift. These are proposed meeting questions, not NOAA instructions or automatic responses to a threshold. Keep four business questions separate from the gauge explanation: - Which equipment and staff are already committed according to current company records? - Which service areas have a reviewed relationship to this gauge? - Which responsible person will assess any preparation proposal? - What evidence would require that person to reconsider the current plan? The [restoration intelligence overview](/intelligence/restoration-and-water-fire-damage) places those questions within a broader preparation process. This article supplies the reading discipline for one source. It does not prescribe standby quantities, deployment locations, or a threshold-based dispatch rule. A river gauge cannot establish damage, insurance coverage, customer authorization, safe access, or suitable equipment settings. Keep those decisions with the responsible professionals and the relevant site records. Do not write them into the meeting note as deductions from stage or flow. ## Leave a note the next shift can read End the reading note with the exact observation, its time, the forecast reference if used, and the thresholds compared. Add the source-access time and any missing units or uncertain references. Separate those facts from the manager's preparation decision. Keep the original training or source sheet alongside the explanation. If someone corrects a unit, retain the correction and its reason. The next reviewer should be able to distinguish a source update from a change in how your team interpreted it. The [business memory guide](/articles/business-memory-for-ai-agents-guide) explains why source records and corrections belong together. For a restoration team, that means preserving what the meeting read and what the responsible person decided. It does not mean converting a gauge number into a loss forecast. Scale With Search can discuss a written scope for organizing that source-reading handoff. Bring one example note, its source references, and the decision boundary your team needs to preserve.
